LLMs often fake drug knowledge based on word structure, study finds

Researchers from the University of Texas at Austin, Northeastern University, and The University of Texas MD Anderson Cancer Center have discovered that large language models often exhibit knowledge of drugs based on their linguistic structure rather than actual pharmacological understanding. They utilized the Olmo model to investigate this phenomenon, finding that LLMs tend to infer drug properties from word morphology rather than possessing genuine domain-specific knowledge. AI

IMPACT Highlights a critical limitation in LLMs' domain-specific knowledge, potentially impacting applications in healthcare and drug discovery.

    A model can sound like it knows a drug—even when it doesn’t.

    A model can sound like it knows a drug—even when it doesn’t. Researchers at @utaustin.bsky.social, @northeasternu.bsky.social, & @mdanderson.bsky.social found LLMs often lack drug-specific knowledge and instead lean on morphology. They used Olmo to trace why. 🧵 buff.ly/PuyfnCq
